Jonsbo ZA-120B (Infinity Sides, Dual Middle Ring, Mushi's Choice) is a 120 mm PWM-controlled case fan with ARGB lighting and a 4-sided “infinity mirror” frame, designed to deliver both solid airflow and a striking RGB look in your PC build. It spins at 700–2400 RPM, provides up to ~62.4 CFM airflow with moderate static pressure, and uses standard 4-pin PWM + 3-pin 5 V ARGB connectors — making it suitable for radiator cooling or general case ventilation while adding a luminous aesthetic to your system.
